Raman measurements on gamma irradiated chestnut fruits
Antonio, Amilcar L.; Cabo Verde, Sandra; Cerqueira, M. FátimaIrradiation for food preservation is on use in several countries for different types of foods: fish, meat, vegetables, etc., with its application accepted and regulated by national and international food safety agencies. In this work an irradiation preservation process was applied on chestnut fruits, studying its impact on fruit characteristics. Here, we applied Raman scattering measurements on two varieties of...
Fostering E-beam food irradiation
Cabo Verde, Sandra; Antonio, Amilcar L.; Santos, Pedro; Redondo, Daniel; Teubib, Pamela; Falcão, António N.There is an ever-increasing global demand from consumers for high-quality foods with major emphasis placed on quality and safety attributes. One of the main consumer demands is for minimally processed foods that are highly nutritive but low energy-dense and are natural foods with no or minimal chemical preservatives. Extending the shelf-life of food products, while improving the food safety and quality, will ha...
Target specific post-harvest treatment by gamma radiation for the microbial saf...
Meneses, Márcia; Antonio, Amilcar L.; Cabo Verde, SandraThis study aimed to assess a specific gamma radiation dose to be applied as a post-harvest process to guarantee the microbial safety of two medicinal plants, Melissa officinalis and Aloysia citrodora. Dried plants treated with gamma radiation indicated that a dose of 5 kGy could be applied as a post-harvest treatment process of M. officinalis and A. citrodora, assuring the microbial safety of dried medicinal pl...

Combined effects of irradiation and storage time on the nutritional and chemica...
Cardoso, Rossana V.C.; Carocho, Márcio; Fernandes, Ângela; Barreira, João C.M.; Cabo Verde, Sandra; Santos, Pedro M.P.; Antonio, Amilcar L.Abstract: Portobello variety of Agaricus bisporus mushrooms, appreciated for its taste, makes it desirable to be eaten fresh and also as flour in soups and gravies. Gamma and electron-beam radiation at four doses (1, 2, 5, and 10 kGy) were used to analyze its preservation effect on Portobello mushroom flour. A proximate analysis, as well as the impact on fatty acids, tocopherols, soluble sugars, organic acids, ...

Food irradiation: where is the limit?
Antonio, Amilcar L.; Cabo Verde, SandraFood irradiation persist as an underused technology in several countries, namely in Europe region, where scientific misconceptions about the technology are wide spread in the population, including in more educated persons. Also, EU regulations are quite old (from 1999) and contribute, in some way, to maintain this status quo. On the last years we have been validating the use of this technology in several food p...
Castanea sativa shells and fruits: Compositional analysis by proton induced X-r...
Corregidor, Victoria; Antonio, Amilcar L.; Alves, Luís C.; Cabo Verde, SandraChestnut fruits, from Castanea sativa Miller species, have been previously characterized mainly to study the nutritional and biochemical parameters, with mineral contents receiving less attention from the researchers, although these minerals are essential for several mechanisms in human body. In this study, a detailed elemental compositional analysis was performed using Proton Induced X-ray Emission (PIXE) to c...
Alimentos tradicionais e inovação: uso de atmosferas modificadas e radiação ion...
Pinela, José; Barreira, João C.M.; Barros, Lillian; Cabo Verde, Sandra; Antonio, Amilcar L.; Oliveira, M. Beatriz P.P.; Carvalho, Ana MariaO crescimento do setor dos vegetais embalados prontos a comer tem levado à introdução de novos produtos e à adoção de tecnologias de conservação mais eficientes, seguras e sustentáveis. Neste sentido, este estudo teve como objetivo avaliar a eficácia de diferentes atmosferas de embalamento e de diferentes doses de radiação ionizante na conservação de azedas (Rumex induratus) armazenadas a 4°C durante 12 dias. A...
Food irradiation as a key to reduce food waste and guarantee food safety
Antonio, Amilcar L.; Ferreira, Isabel C.F.R.; Santos, Pedro M.P.; Cabo Verde, SandraFood waste is being in the focus of recent global policies, to tackle food scarcity and to overcome “nutritional poverty” in several countries. Otherwise, a global food market is being the key to make available several products to different populations. These vectors for food policy must be supported by several orientations, to attain their final objective: better and enough food for the world population. For t...
